Application led January 24, 1923. .Sex-,iai No. 614,645. i

The object of this invention is to provide a machine for making swabsor'daubers for applying liquid polish to foot-wear, of the type used asStoppers vfor bottles containing the liquid, but it is to be understoodthat the invention is not limited to the manufacuse mentioned. s Y

So far as this particular `machine is rconcerned, it operates upon wiresof the proper length to'forn'i ahandle or part of a handle, bends oneend or them about a strand of lilaiientousmaterial, and then cuts thefilamen# .tous material between adjacent wires, so that each wire issupplied with a tuft 'of the vlilamentous material vwhich in usecarriesl a charge or supply ofthe liquid to be applied.

The invention consistsof a machine having a wire carrier moving past afilament feeder and in conjunction with a twisting head which twists anend of the wire'about the lilament, whence the thus assembled partsarepresented to a wire clenchingelement, .and

then to a cutter which severs the filament foreach wire, after which thethus :finished device is discharged, as I will proceed to ,e X- plainand finally claim.

The maze' made.

'The material from whichthe tuftof the swab or dauber is formed may beasliver or roving of wool or other suitable filamentous or fibrousmaterial, althoughvthe invention isnot limited in this respect; b ut theinvention will be explainedA here on the basis of the use ofthe materialin strip fornito which the wires are applied, and `then the stripsevered into individual tufts or pieces. `Nor is' it necessary that theswab or dauber should be made of filamentous material since obvious-'lyit'n'iight be made of absorbent ,material in felted form or any othersuitable form.

Tliewires, in the present illustration, are first cut to properlengthand -hand-.fed to the machine, and by the machine'the tutt and wires areunited and the 4swab or dauber finished ready to receivel lany suitablehandle, such as a cork or bottle stopper'.

AIn Figi12 is shown a'tuft a with-the wire 7) twisted about it, as ,shownat V@and in Fig.

13 the wire is shown as flattened, clenched or comliressed about thetuft. Y tuftis shown asexpanded into ball form with the wire enclosedtherein, and at its opposite end this wire is embedded in ya bottlestopper d of corlghaving a wooden cap @cemented or ,otherwise` appliedthereto and serving as a handle for useA .in applying the liquidabsorbed by the tuft.

The wire carrier.

1 is a table, suitably supported on legs 2. 3 isa i` ire carrier,ymounted on a shaft 52 which is supportedin bearings 73 and 133, Fig. 1,mounted on the table "l and in albearing 91 mounted ina cross-piece? 7of va frame including kthe beams 7 4.and'7 8 extending lateral-ly 'fromthe table and bolted thereto, this cross-piece 77 being bolted to the'beams 74 and 78. lThisy wire rcarrier is a circula-r,

spoked structure, having a rim 300 provided with a central groove-30lflanked on either In 14 the Cil side by the toothed flanges 302 and5503: and the toothed flange 303 is provided with the radial grooves304. r1`he spaces between adjacent teeth have at their bottoms thegrooves 305, Fig. El, to receive the Wires Z) and the teeth carry theWires forward in the direction of of the arrow, Fig. 2, as the carrieris turned, and these spaces are herein referred to as transverselyarranged peripheral Wire holders. l is a brace fastened to the table 1and to an upright 44C, also fastened to the table, and havingl theright-angled top portion il@ to which are fastened the fingers l5 and1fl2 that entend partly over the carrier and serve to prevent the Wiresfrom jumping` out of the carrier.

@n shaft 52 is mounted a pulley S2 by which the shaft n'iay be driven.lt will be understood that the carrier 3 does not turn with the shaft52, but is mounted loosely thereon and is Agiven a step-by--stepinet-ion in any suitable Way. One mechanism for givingthis step-by-stepmotion consists of a lever pivoted at 13 to a stand mounted on thetable.rhis lever is provided with a dog 37 pivoted thereto and backed up by s;38, the dog engaging the teeth of the one by one as the lever isactuated. lever extends into the path of i'novenient a cam 42 turningwith the shaft 52, and provided with a roller'al in contact with thecam, see Fig. 5.

rlhe groove 301 of the carrier 3 receives a Wire hold-down, shovvn aband 60. at the right hand side of the machine, see Figs. 1 and 2Whichserves to positively hold the Wires on the carrier after the Wires havebeen applied to the dauber or swab material and While this material. isbeing' cut7 as hereinafter explained. This hold-down band (l0 issupported on a pulley 128 arranged above the carrier and a 4 pulley111() arranged heloiv the table 1 in a bracket 585 and a band if. enerpulley 61 arranged to the ri f ht oi. carrier, Figs. 1 and 2, and naomiforked slide 5 adjustably arra ged on a snpport 5 mounted on the table 1and having a back-stop 63. Of course any suitable iii/ans may be usedfor tighteningthe bnn d or takin .fij up slaclr therein.

lVhilc I prefer to use both the toothed Wheel structure and the grooveand belt to hold the Wires, it is within my inve tion to dispense witheither.

The twister head.

21 is a vertically reciprocating?, racl; bar mounted in a bracket 12esupported on bracket 8G extending` from the tabl This rack bar isconnected with a bar 30 n'iounted to slide longitudinally in brackets 36and 123 and engaged by a lever 125 through the inediurn of a slot andpin connection 125X otherwise as necessary or convenient. This lever 125is pivotcd at 81 on brackets 65 and 139? Fig. 3,'fastened beneath thetable 1. rl"he lever has applied to it or its pivot an arm 17 on whichis an adjustable countervveight 16. rlhe other or outer end ofthe leveris connected with spring 66 depending from a bracket 29 on the bracket12e. The pivot 81 extends over toward the drive pulley b25 and at ornear that end has fixed to it .an upright arm 92 provided with a roller95 which is engaged by a cani 96 fast on the sha-ft 52, so that in therevolution of said shaft the cam will act upon the roller and serve toroch the pivot in its hearing' brackets and thereby oscillate the lever12.5 against the tension of its spring;l 66, and and down in itsbearings.

25 is astand fixed to the braelcet 124. and in this stand isstationarily mounted in a beatir g; 20 a hollow spindle 24 and securedtherein by a set-screwv 'l` his spindle has a flaring mouth 240 forfeeding the sliver or roving` or strip which i to he formed into dauberssivabs. This spindle has its end opposite the flairing` end providedWith a rh. Oe 2%1, and this flanged end is recessed to receive tubularinset 2112 provided with an inclined face Harige 2/-13 having` a radialslot 2&4. in its Widest part. 2115 is a set-serein7 tapped in the flange241 and engaging the inset to hold it stationary. On the spindle ismounted a cylinder 22 having,` a countersunh recess 220 to receive theflangedendA of the spindle. This cylinder is provided with a toothed 221which is meshes by the toothed rack bar21 and thereby given a rotaryreciprocating inotion on the spindle an airis or stud-s iaft. is atwo-diameter or flanged head mounted eccentrically on the cylinder bymeans of a stud turning` thereon and turning with the cylinder.V ldlhena nfire handle member 7) is inserted in the slot 244i radially., withits leadu in en d inserted in the tii'fti'foi'iiiiiii; material. asshoivn in Fig'. 16., and the cylinder is causaal to rotate in thedirection indi ated by the arrow. Wig. 16 the head 28 sweeps around theinserted ivircl and bends t-he end of the Wire into a loop Whichembraces the sliver or roving or other tuft or swabdorniing strip andunites the tivo, as shoivn in Figs. 12 and 18. Because of the functionsdescribed the parts shown in detail in Figs. 10 and 117 and 16 to 20,may be appropriately designated a twister hea-d.

Referring; to Figs. 16 to 20, it will be seen that the high point of theinclined face flange 24:3 serves as an abutment next to its slot 24M:upon Which the initial bend of the wire is n'iade and thereafter in thecontinued rota tion of the twister head the Wire is coiled about thetuft material, the inclined face of the flange serving to direct theWire in coil forni, and this inclined face having its lovv pointimmediately in advance of the high point containingthe slot. When thecoil conse uentlv inovc the rack bar no 280 and lll) of the product.

The bracket 29 maybe extended to the left Fig. 2) and be provided 'atfor ynear its outer end with a. hook-shaped element to afford al supportand guide for t-he sliver, strip or strand of'tuft-forming material.'`

The 'guade- It will be understood that the strip or strand of materia-lto be lused is inserted into the flared end of the hollow spindle so asto extend out of its opposite end, and the wires applied one by one tothe twister head and twisted about the strip at regular intervals, andthen engaged by the spring guide fingers 31 and 32, the latter longerthanthe former-` at their ends nearest the twister head, and curveddivergently to facilitate the passage by U-shaped clips 33 andsimilarclips 143, and the fingers are respectively supported:I upon arms 45 and142 projecting from portion 44X,

and the stand 34; yThese fingers are spaced apart Asufliciently topermit-the passage ofthe wires and. hold them level. In the beginning ofthe operation. the wired strip or strand'is hand-fed. As the firstformedwire reaches the carrier 3,1it drops from the fingers intoA theteeth of the carrier and th'ereaftervthe carrier serve-s tor feed thestrip and theattached wires L forward untilthey are caught'by the band60.

As the carrier revolves, the wired strip is n carried forward beneathitshold-do'wn until-y the carrier passes from the band 60 and then, thestrip having been severed, as will be presently described, theindividual' dau'bers'or swabsfall from the machineinto a suitableieceptacle appropriately placed to receive them, and are ready to havethe Cork and handle elements applied thereto. o

11s each individual wire is discharged from the `guide fingers, it isgripped by a plunger 50, Figs., and 4, normally projectedbya spring 51and the wire is thereby straight-v ened adjacent to its connectionwith'thetuftforming material. This plunger is carriedvr in the frame49'mounted on abase 48 and this 'base Vris carried by a slide 47 mountedin guides 464 havingtlhe face pieces 46X, and this slide isconnected'with' a'yoke 53v mounted onvv guide rods 68` whichproject'through ears 69A on the yoke and are provided with springs G7 normallytending lto elevate the slide.
